so that there is no chance of penetrating the aircraft's hull. That is the only point I concede.

Don't concede that, either. All that "hull-puncture" stuff is foofoo dust. There's PLENTY of cabin pressure to go around, and at least 2 GE jet engines to provide it.

Really think a 9mm hole lets air out faster than 2 jets can pump it in??

small technical quibble: It isn't the air let out by a small hole that causes the problem. It is the pressurized air NOT let out pushing against a skin that has been compromised by that small hole that might pose the catastrophic hazard.
